Yes they don't like to be overheated. When the warning comes up to stop and turn off the engine, you cannot keep driving, not even a little bit.

Replace the parts and carry on. There's no battle to be won here. Plastic cooling system components are the norm on all cars now and they fail from time to time. My '13 Sonic has been though 4 thermostat housings, along with the rest of the cooling system mostly, some of it twice. It doesn't even have a temp gauge from factory, just a warning light. My niece drives the car now and she knows to be aware of it, had a plastic heater hose fitting pop on her the other day, because she stopped when she saw the coolant leak, $13 later I had it back together and she's on her way. Unfortunately this is the way engineering is going on new cars, it sucks but it is what it is.

 

[QUOTE=Peterinio;2605776]I recently posted about my December purchase of a 2017 F-Pace S with 125,000km and subsequent catastrophic failure after only a week due to overheating caused by the deterioration of plastic cross over pipes under the supercharger. The vehicle was purchased privately so no recourse there. Before purchasing though, I had the vehicle thoroughly checked out by a Jaguar dealer, who says these things can easily happen without being detected beforehand. They also indicated that since the vehicle is out of warranty Jaguar is not likely to do much if anything.
There was no real warning that this was happening until it was too late. The heat gauge went from reading narmal to overheated in about 2 seconds and then it was too late. The dealer has indicated that it's 99% likely the engine is done which would mean $20-$25k to replace the engine. Since this event occured I have learned that this is a common issue with this vehicle. Constant hot and cold causes these plactic pipes to expand and contract and eventually break (around the five year mark), which is unfortunately what happened to me. The heat guage not providing proper information is apparently a known issue as well on this vehicle.
It seems that manufacturers of high end vehicles are not being held accountable for building vehicles that are destined to have major failures just outside of the warranty period. This situation appears to be very common and known to Jaguar which brings me to the reason for this post. I realize I am stepping out on a limb here but I am asking F-Pace owners that have experienced anything like this to reply or if preferred, to direct message me if confidentiality is important. This would be specifically for North America but it would be important to hear from anyone, anywhere in the world that has experienced these things. At this point it is necessary to understand how widespread this may be in order to determine the best course of action.

Thank you for your participation. Peter[/QUO I have a 2018 Jaguar F Pace s purchased with just over 40,000 miles owned it for an exhilarating wonderful year well almost. My coolant crossover pipe blew out on the freeway I was able to pull off and add water to get the rest of the way home had the vehicle towed the y-pipe replaced for $2,500 only to find out that the head gasket was blown and then I was looking at another 6,000 to $8,000. I can't describe the disappointment I feel in having a dream car of mine turn out to be a time bomb. And the worst part is Jaguar knew about it and did nothing! Yes I am definitely in on holding them responsible thank you so much for your post my email is attached.

 

I had to replace my coolant y pipe for the second time due to failure. From what I can tell, they are on their 3rd design for this. I’m also looking to bring legal action, as JLR refuse to acknowledge faulty y pipes that have become a known problem. I’d love to start a list of people who have had similar problems. I have a 2017 F Pace S. This engine was also used in the F Type, which is having the same problem.

Same thing happened to me (I have an F-Type, not an F-Pace, but same engine and display).

The problem is not necessarily that the coolant system fails with all of those older plastic pieces. I have a remanufactured engine (reman) with all of the weaker plastic pieces replaced with their metal counterparts.

The problem is when a coolant hose pops (happened to me last week on the freeway), or a plastic pipe fails, and you dump all of your coolant, you have a false sense of how much time you have to pull over (sometimes finding a safe place is hard when it happens).

The dashboard digital display keeps the coolant temperature gauge at the midpoint until 110 degrees Celsius before it increases. By the time your dashboard coolant temperature gauge says your engine is overheating, it’s too late. Your engine is cooked.

i now have real-time gauges displayed on my mobile phone connected to a Bluetooth OBD reader. It tells me the current temperature of the coolant and oil every second (I use an app called torque pro). I don’t go anywhere without it.

if there’s any legal recourse here, it should be primarily focused on the temperature gauge on the dashboard staying at the midpoint until your engine is already cooked.

 

Brett Law is filing a Class Action for this issue.

Only

2013-2017 Is this issue not on models after this.

 

Coz 2017 is around the time that JLR replaced the problematic Y-pipe (and others) on the AJ126 and AJ133 with a new design, from a pipe with a seam welded horizontal join to a smooth one piece pipe with no such join. Still a bit problematic, mainly at the seals where the pipe plugs into the block, but nowhere near as bad as the previous design.

 

Right there was an issue and it was fixed. I don't know what payback people want for a car that's been out of warranty for a decade, but people love to sue.

 

Good point about the temperature gauge that everyone needs to understand. We do NOT have a gauge! We have an "indicator". The response of the needle is purposely damped in the mid-range as posted above. If and when the needle does move it's now too late and the engine is already over heated.

In years past we had a forum member run some tests proving the needle stayed in the middle over a wide range of coolant temperatures. Why was this done? Don't know but the rumor was to reduce the number of warranty calls when the car had no problems. Owners brought their cars in because the temperature indicator needle was moving around. Just like it's suppose to!

I do what was posted above and I use the very cheap Torque Pro App. Which allows you to get real time data like coolant and oil temperatures. Cambo also made a custom PID pack years ago just for the later Jaguars which added things like boost and transmission temperature. Pretty handy!

BMW has been doing that since the late 90s. On modern cars, with the advent of electronic thermostats, variable water pumps, etc, we can't have the temp steady on the gauge because it isn't actually steady. Customers would be worried seeing it moving, so as long as the actual matches the desired, it's in the middle. Some cars have gone away from a gauge all together and just give a warning light, or like my audi displays the oil temp, not coolant temp as an actual readout. We also use different temperature settings for the block and head based on emissions, so what is the temp we should display? The 195 at the cyl head, or the 220 at the engine block when both are correct? Just put it in the middle, so you know it's where it's supposed to be.
